Hi - I have a 128K Mac with a Levco Monster Mac 2MB upgrade card installed in it, and somewhere over the years the covers on the EPROMs on the Monster Mac card have come off... and now the machine comes up to a sad mac icon with an error code of 0180D7; which my brief google search indicates that it's failed a ROM test - unsurprising considering the lack of UV protection on the EPROMs. I don't think the original Apple mask ROMs (they are mask ROMs, aren't they? Not EPROMs? They have no window on them...) are bad; just the EPROMs on the Levco board - so what I need is an image of that -
